Rewrite the following using a thermochemical equation with a deltaH value: a) The standard molar enthalpy of combustion for propane is -2220kJ/ mol.

Answer 1

What do you mean?

Answer 2

Your post says to rewrite the following using a thermochemical equation but you don't give anything to rewrite. Sorry. Now I see the combustion of propane.
C3H8 + 5O2 ==> 3CO2 + 4H2O dH = -2220 kJ

I have also seen these written as
C3H8 + 5O2 ==>? 3CO2 + 4H2O + 2220 kJ

Answer 3

ok thanks a lot for your help but why did you put a question mark after the > in the equation you gave?

Answer 4

I made a typo.The question mark key is next to the > key and I hit both at the same time.

Answer 5

Ok thanks again for all your help :D
